The present invention, relatesto oil--burn-. ers, and more particularlyfto' that type fin which a steam-jet -isernployed for the disin-: tegration and 'volatilizationl of the hydrocarbons, the `two thereafter entering they combustion chamber as avaporizedffspray;

primary object of our `invention isfthe alignmentnwith thedischarge 24 foi-medep-y positely.1 theretoV :in the block', the said .port andexihaust being both substantiallyv tane.. gentially-arrangedlrelative tothe rotor, as shown in Figure 1. f

v The'foilsupply.line-25 -is-tapped into the block andcommunicateswith-a port 26, a second-port v27 being.` formed in. the block fat righteanglestothe port .26 andccmmunicatAF ingwthercwith. `Arsrnajller por-t28 communicates with,..the xport 27 and the. mining .chamber', the-'port 28 having ayalve-seat 29 into which the conical.- end4 of thet..val.vestem .30borne by theoil needle-valve .31 istadapted to seatathrough which' the `oil-flow. .to fthe chamberbds-controlled. i' i The rotor` 12 is' preferablyT of cylindrical form,l as shown inFigure 2,Qandis designed to rotate .lfreeiy .uport .its..bearings .within.its chamber, it being-.feo .constructed..,asnto. provide a central cylindrical body uniting two oppositely disposed frustrurn of cone bodies, thus constituting a reduced portion 32 and flared flanges 33 and 34, thereby providing an annular space between these bodies and the central portion of the bore 2 constituting the mixing-chamber 5.

The steam-jet entering the port` 23, as regulated by the valve 20, impinges against the peripheral surface of the cylindrical portion 32 of the rotor 12 causing it to rotate at high velocity in the direction of the arrow in Figure 1, while, simultaneously, a jet of yoil is sprayed against the rotor from the port 28, through the proper manipulation of the necdlefvalve 31. The oil as thus sprayed and received by the rotor is given, initially, the impulse andvelocity of this member spinning at high velocity and is thrown therefrom through centrifugal action with force against the wall of the bore, from whence it is deected and borne along at an increasingvelocity to be met by the inrushing steam-jet and thoroughly disintegrated thereby and commingled therewith and passed on, as a completely volatilized product, to the discharge-port 24 and thence ejected under high pressure through the burner-tip, or nozzle, 35 into the combustion-chamber, where the intense heat decoinposes the steam constituent into its component gases, hydrogen and oxygen, combustion elements greatly increasing the fuel value.

provision of means for the thorough-incor-` poration of thefoil and stearnfmolecules pre-i liminary toltheir ejectment into the: com-- bustionv chamber. y

1n the accompanying drawings, .forming a partjof this specification:

Figure lis a top plangviewk ofour oilburner, showing kthe relativeiarrangement of the oil and'steam inlets an'dtheir respective control valves, the rotorffandfzthewmixingf chamber, parts being. broken away fon clean ness of illustration; and s Figure 2 is a transverse sectional view takeng through the burner block, showing the iniXing-'chamberl and the? vrelative arrangement thereto of the steam-inlet, the rotor and the discharge outlet leading to the burner nozzle, the section being indicated by the line 2-`2 of Figure 1.

Referring with greater particularity to the drawings, in which a preferred embodiment of our invention has been illustrated, 1 indicates, in a general way, the burner-block having a central bore 2 into which is tted a pair of oppositely disposed flanged plugs 3 and 4 forming therebetween, and centrally of the block l, a mixing-chamber 5.

rEhe flanges of the plugs 3 and 4 are secure'd to the upper and lower faces, respectively, of the block 1 by a plurality of machine screws 6 and?, and are provided centrally thereof with openings 8 and 9 adapted to receive thrust-bearing members 10 and 11 formed on opposite sides of the rotor 12, the rotor being revolubly supported by means of said bearing-members and supporting-studs 13 and 14 provided with conical ends 15 and 16 adapted to lit within corresponding conical seats formed in the rotor bearing-members.

The steam-inlet pipe 17, leading from the supply source, is tapped into a port 18 in the block 1 and a second 19 is formed in the block at right-anglesto the port 18 and communicating therewith, the port 19 being tapped for the reception of a needle-valve 2O having a stem 21 provided with a conical end adapted to seat in the tapered seat 22 formed in a port 23 which communicates Vwiththe-port-y19 land Ythe chamber 5 of thek burner, the port 23 Ibeingg.arranged in axial.

We claim:

l. An oil burner of the character described, comprising means forming a mixing-chamber, a rotor in said chamber, said rotor consisting of a reduced central section having oppositely disposed flanges, means forming adjustable thrust-bearings for said rotor, a valve-controlled steam-port and a valve-controlled oil-port communieating with said chamber at relatively remote points, said steam-port being arranged in tangential relation of said rotor, and a discharge-outlet leading from said chamber in substantially axial alignment with said steam-port- 2. An oil burner comprising a block hav ing a mixing-chamber there-in, a rotor in said chamber, adjustable thrust-bearings for said rotor, the said rotor being of substantially cylindrical form, a valve-controlled steam-port and a valve-controlled oil-port in respective communication With said chamber, said steam-port being arranged in tangential relation to the peripheral surface of said rotor vand adapted to discharge a steam-jet tangentially thereagainst to cause said rotor t0 spin at high velocity, said oil-port being arranged to communicate with chamber at a point spaced away from said steam-port and adapted to discharge an oil-jet into said chamber and against said rotor, and a discharge-outlet arranged to communicate With said chamber at a point opposite said steam-port.

3. In an oil burner of the class described, a block forming a burner housing, a bore in said block, flanged plugs in said bore, the said bore and plugs forming a mixingcliamber, a rotor in said chamber'carrying thrust-bearing members, said rotor being of substantially cylindrical form and so constructed as to constitute a central cylindrical section uniting oppositely disposed rustoconical bodies, bearing-supports carried by said plugs adapted to engage said rotor bearing-members, valvecontrolled means for introducing a steam-jet into said cliamber in tangential relation tothe peripheral surface of the rotor, a valve-controlled means for introducing an oil-jet` into said chamber, and a discharge-outlet carrying a burner-tip communicating with saidchamber at a point remote from said steam and Oil jets but substantially in axial alignment with said steam-jet.
